To ctZZ whom, it may concern.-

Be it known that I, ROBERT W. HALL, a citizen of the United States, residing in Cambridge City, in the county of Wayne, and in the State of Indiana, have invented a new and useful Double-Shovel Garden-Plow, of which the following is a'full, clear, and exact specification of my preferred construction, which when taken in connection with the accompanying drawings, forming a part thereof, will enable others skilled in the art to which it appcrtains to make and use the same.

The object of my present invention, broadly speaking, is to providea garden-plow of simple and durable construction, positive in action, easily operated and controlled, and to generally improve the construction and operation of devices of this'general construction.

A more particular object of the invention is to provide a new article of manufacture,-a double-shovel gardenplow to be manually propelled and manipulated without the intervention of other motive power.

A more specific object is to provide a double shovel garden plow with means apart thereof whereby it may be. propelled forwardin advance of and "by an individual, the means.

for applying the power to the point ascertained to give the best results-thatis to say, to equally balance the plow to obtain a maximum of ease in its propulsion and manage-- ment and to obtain the highest degree of efficiency in operationand in the'results derived therefrom.

Another desideraturn which I have accomplished is in the positioning of two interde pendent shovels, which I have found to give the best results, and by their disposition with reference to each other and to other parts of the plow, their inclination, and the manner of their attachment will not be more laborious to manipulate than similar plows of a single shovel, and, finally, a further object is to provide a bodily-operative garden-plow comprising in its composition a minimum of parts, thus dispensing with all unnecessary weight and expense of construction, to provide means for relieving thehands and arms of the operator by employing the hips and abdomen and the weight of the body for supplying. the motive power, thus leaving the hands and arms free to manipulate the operations of the plow, and, further, to generally simplify and improve the construction and operation of plows of this general character.

My invention consists in the form, construction, and disposition of the severalessential elements and subsidiary devices in the organization of plows of this class and in the composition of the-several parts, which will presently be particularly explained and described in detail.

For a more comprehensive understanding of my invention 1 will now refer to the accompanying drawings, showing my preferred construction, in which Figure l is a view in perspective of'my entire invention. Fig.2 is a plan view, partially in section, showing my plow-beam and its related position with reference to parts connectedtherewith. Fig. 3 shows in elevation oneor the other of the two standards of my plow, with some of the parts connected thereto in section. Fig. 4: is a longitudinal section of my propelling means, and Fig. 5 is a detail viewof one or the other of the clips.

Similar characters refer to and denote like parts throughout the several views of the drawings.

With the above-designated views in mind I will now take up the description of myinvention with exactitude and willrefer to and describe the various parts as briefly and compactly as I may.

Referring now to the drawings in detail, the letter A denotes the left and A the right hand members of my plow beam, whose forward portions are parallel and are some distance apart, being connected in the rear oftheir center portions by a hollow spool placed between said members to hold them apart, and the bolt A which passes through suitable apertures in the members A and A longitudinally and through. the spool, se-

cured by a nut on one end of said bolt, to bind the parts together. In the rear of the spool the members A and A flare outwardly some distance and are then bent parallel at their immediate end portions. It will be noticed that the rear extension of the member A is somewhat longer than is the corresponding portion of the member A for the purpose of advancing one of the blades ahead of the other, as will presently appear, and near the end of each of said members A and A is formed a hole for the insertion therethrough of the respective bolts 7 and 7.

The letter A designates the cross member of the beam disposed at an angle horizontally, having forwardly-turned end portions with holes therethrough for the respective bolts 7 and 7.

The letters B and B denote the two standards disposed at an angle vertically and which are of identical form and construction, except that the former is of a slightly greater length, for the reason which will presently be apparent. Each of said standards B and B, I prefer to forrn of two identical portions of flat material spaced apart at their upper ends to receive the handles hereinafter referred to and extending down parallel with each other some distance apart and held from contact with each other by the spacers b 7), as shown in Fig. 3, and secured together by the rivets or bolts 1 above and 2 below in the standard B and 1 above and 2 below in the standard B, each of which bolts or rivets pass through one of said spacers Z2. Somewhat below the central portions of the standards are holes therethrough for the bolts 7 and 7, respectively, from which it will appear that the rear ends of the members A and A may be placed between the members of the respective standards and also that the member A may be positioned as in Fig. 2 and that the bolts 7 and 7 may be inserted through said holes in said members and secured by tightening the nuts thereof, which will secure said members together, as in Fig. 2.

Near the forward ends of the members A and A are formed horizontal oppositely-disposed round apertures to receive the horizontal axle O, which latter has its end portions threaded and is of a length to extend across the space between the separated ends of the beam through said apertures therein and some distance out therefrom at each side.

The letter D denotes the ground-wheel, which is revolubly mounted on the axle G between the ends of the beam, as shown. The wheel D is retained centrally in position on the axle C by the nuts E and E, which are run on the respective ends of the axle C and are positioned almost in contact with the ends of the hub of the wheel D, with the ends of the beam contacting with their outer faces.

The letters P and P denote the two clips, (shown in Fig. 5,) formed of a flat material and consisting of the lower eye portions,\vhieh are placed over the respective ends of the axle C and then extended up aid and slightly forward, where they are given a quartertwist, and immediately above said twists they are bent at right angles to extend rearward and upward and with bolt-holes formed therethrough near their rear ends for the bolts 4- and 4t, respectively. The said clips being thus positioned, the nuts 3 and 3 are run on the respective ends of the axle and tightly contacted with the respective clips l and I", thus securing the ends of the beam and the eye portions of the clips between the said nuts 3 and E and 3 and E, respectively.

The handles of my plow are denoted by the letters F and F and are provided on their rear ends with the respective handholdsj" and f, and said handles are disposed at an angle with theirforward ends positioned in the angles of the respective clips 1 and l and secured thereto by the respective bolts -.t and 4:, as shown. Toward their rear ends the handles are secured in the upper ends of and between the two members of the respective standards by the respective bolts 5 and 5, as shown.

The letter Gr denotes the cross-bar uniting the two handles slightly in the rear of the ground-wheel, havingits ends bent rearward, with apertures therethrough for the respective bolts 6 and 6, by which said bar (l is secured to and between the handles, as shown. Through the center of the bar (-2 is formed a square eye for the purpose hereinafter stated.

The propelling mechanism, (shown in section in Fig. ,)consists first of the hollow rod or pipe H, having a squared forward portion 7t of less diameter than the pipe H, of which it is a part, which square portion is adapted to be inserted in the eye of the bar (-i and locked therein by the key Z, which key is located in an eye formed through the forward end of said portion /1 Near the rear end of the rod H is a threaded aperture through its shell on one side to receive the threaded shank of the fiy-nut l.

The letter J denotes the adjustable rod, which is of a size to neatly telescope within the rod .H and by means of the fly-nut l may be secured at the point desired longitudinally. On the rear end of the rod J is secured the body-plate K with said rod firmly secured in its center. The plate K is formed, preferably of a stiff but somewhat flexible material (such, for instance, as spring-steel) curved in the segment of a circle with its concave face rearward and being adapted to extend from hip to hip in the front of the operator, whereby a person may apply motive power to the plow by the weight of his body as he follows therebehind in the accomplishment of his work.

The letter N denotes a chain or the like loosely suspended, its ends being secured to lOO the respective handles F andF, and thereby providing a rest for the rod Hwhen it is not in use.

Surrounding therod J is a compressible helical spring 10, with its forward end securedto the rear end of the rod H in any preferred manner and with its rear end secured to the plate K in any preferred manner, and, if desired, the nut I may be loosened, and I thus provide a sprin'g-bearingcontact for the operator of the plow.

It should be'noticed that by reason of the arrangement'of the above-described propelling mechanism I have provided against the turning of the body-plate K, thus at all times insuring its being in its operative position, as shown in the drawings.

Detachably secured to and extending below the lower ends ofthe standards B and B are the respective blades or shovels L and L of any preferred form or construction, with their lower points projecting below the lowermost portion of the periphery of the wheel D. Said blades L and L are secured by the respective bolts 9 and 9, which bolts pass through the prongs formed by the lower ends of the standards and whereby said blades may be adjusted vertically.

The variously-named parts constituting my plow are so locatedand organized as to effect substantially the following operation: Aperson may be positioned behind the plow in the usual manner, grasping the handholds ff" with his hands, and allowing the plate K to partially surround the body at or near his hips. Then by throwing the weight of his body against said plate and walking forward it will beapparent that the plow will be advanced, carried over the ground by the wheel D, and also that by manipulating the handles the plow may be guided and the depth of the blades controlled with reference to the soil they are'intended to disintegrate or work.

While I have illustrated and described the best means now known to me for carrying out my invention, I desire it to be distinctly understood that I do not restrict myself to the exact details of construction shown and. described, but hold that any changes or variations in such details as would suggest themselves to the ordinary mechanic would clearly fall within the limit and scope ofmy inven" tion.

Having now fully shown and described my invention .and the best mode of its construc tion to me known at this time, whatI claim,

between the forward ends of said arms, a pair of standards mounted at'an angle vertically to the rear'corners of said beam each of said standards consisting of two identical members secured together with spaces therebetween at various points for the attachment of other parts of the plow, a clip secured near each end of the axle and projecting upward, apair of handles with their forward ends secured to said clips at apoint above the axle and then extending rearward and upward and each being secured between the upper ends of the respective standards beyond which they extend, a cross-bar uniting said handles, an adjustable propelling device attached to the cen-' ter of said cross-bar and extending to the rear with'means for applying bodily power thereto to move the plow forward, and ablade at? tached to the lower end of each standard, allsubstantially as described.

2. In a garden-plow, the combination, a beam, an axle mounted in the forward ends of the beam and carrying a ground-wheel rev-- olubly mounted thereon between theforward ends of the beam, a pair of clipsone of whichis contacted with the outer face of each of the forward-ends of the beam and over the respective ends of the axle, means for securing I I end of one of said standards, a cross-bar uniting said handles, a hollow rod having its forward end keyed in the center of said crossbar, a chain-suspended between said handles on which said hollow rod may rest, a smaller rod telescoping in the hollow rod and projecting rearward, a body-platesecur ed on the rear end of said smaller rod and formedof a single piece of flexible material, a helical spring surrounding the smaller rod with its forwardand rear ends secured to the end of the'hollow rod and to said body-plate respectively, and means for securing the smaller IIO rod within the hollow rod adjustably, all substantially as shown and described and for the purposes set forth.

3. In a garden-plow, the combination with a double beam having a ground-wheel mounted between'its forward ends and standards dis-- posed at an angle carried by the rear portions of the beam and located one in advance of theothera pair of handles connected by clips to the forward ends of the beam and at their rear portions to'the upper ends of said standards, of the cross-bar uniting said handles with a square central aperture therethrough, a hollow rod having a square forward end portion disposed in said aperture of the cross-bar, a key secured through an aperture formed transversely through the forward part of the square portion of said hollow rod for preventing said rod from being withdrawn from the said square aperture, a chain suspended between said handles to support the rear end of said hollow rod, a solid rod adapt- 5 ed to telescope in the hollow rod, a push-plate secured to the rear end of the solid rod, a helical spring surrounding the solid rod and having its ends secured to the rear end of said hollow rod and to said push-plate, all i substantially as shown and described and for I0 the purposes set forth.

In testimony whereof I have hereunto sign ed my name to this specification in the presence of two subscribing witnesses.
